Description
Technical field
The present invention relates to a kind of energy-saving field, especially a kind of energy-saving low-temperature afterheat generating system.
Background technology
Organic Rankine bottoming cycle is the closed cycle with low-boiling-point organic compound as cycle fluid, due to the thermal efficiency that its tool is higher, is acknowledged as a kind of effective Low-temperature heat utilization techniques.In common low-temperature waste heat power generation system, the weary gas flowed out from decompressor also has certain temperature, this weary gas condenser of directly entering is thoroughly cooled as liquid organic working medium, this phenomenon has a drawback: the partial heat of the weary gas water that is cooled absorbs and is not utilized, and causes the waste of heat.Another one drawback is there is also: in a cooling system in common low-temperature waste heat power generation system, the cooling water flowed out from condenser causes the rising of temperature owing to absorbing heat, in order to make condenser reach more preferable cooling effect, especially in hot summer, the cooling water flowed out from condenser will be typically piped directly in sewer, it is not reaching to the effect of cooling water circulation use, thus causes the waste of cooling water.
Summary of the invention
The invention aims to solve the waste of weary gas heat in common low-temperature waste heat power generation system and the waste of cooling water, thus propose a kind of energy-saving low-temperature afterheat generating system.
For achieving the above object, the technical scheme is that a kind of energy-saving low-temperature afterheat generating system, including organic rankine cycle system and cooling recirculation system.Described organic rankine cycle system includes the electromotor that the afterheat heat exchanger being connected by pipeline, decompressor, weary gas heat exchanger, condenser, gas-liquid separator, liquid organic working medium pump, gas organic working medium pump are connected with described decompressor；Condenser that described cooling system includes being connected by pipeline, cold rinse bank, water pump；The setting height(from bottom) of described liquid organic working medium pump is substantially lower than the setting height(from bottom) of described gas-liquid separator.The gas gone out through described gas-liquid separator separates enter described in weary gas heat exchanger, the liquid that goes out through described gas-liquid separator separates enter described in liquid organic working medium pump.
Described a kind of energy-saving low-temperature afterheat generating system has significant characteristics of energy saving for common low-temperature waste heat power generation system, specifically, a kind of energy-saving low-temperature afterheat generating system is operationally, organic working medium afterheat heat exchanger in described organic rankine cycle system absorbs waste heat heat and becomes high temperature and high pressure gas organic working medium, high temperature and high pressure gas organic working medium flows to described decompressor and promotes decompressor to rotate, the electrical power generators described in the rotation of described decompressor and then drive；After the most weary gas weary gas heat exchanger of entrance that described decompressor flows out, the partial heat of the most weary gas is passed to the gas organic working medium gone out through described gas-liquid separator separates；Cool down from the condenser described in the secondary weary gas entrance that described weary gas heat exchanger flows out, be probably neat liquid from the state of the organic working medium of described condenser outflow, be also likely to be gas-liquid two-phase；From the gas-liquid separator described in the organic working medium entrance that described condenser flows out, the gas organic working medium gone out from described gas-liquid separator separates enters after weary gas heat exchanger absorbs the heat of the most weary gas and flows into described gas organic working medium pump again, and the liquid gone out from described gas-liquid separator separates is directly entered described liquid working substance pump；Described afterheat heat exchanger is reentered after described gas organic working medium pump effluent air organic working medium is converged with the liquid organic working medium flowed out from described liquid organic working medium pump.Described cold rinse bank is entered after the heat air cooling of the cooling water condenser absorption weary gas of secondary in described cooling system, the cold water of described cold rinse bank is squeezed into described condenser and then completes a cooling circulation by described water pump again, reaches the purpose of cooling water circulation use.

Detailed description of the invention
Below by detailed description of the invention, technical scheme is described in further detail.
Referring to Fig. 1, this utility model embodiment provides a kind of energy-saving low-temperature afterheat generating system, and this one energy-saving low-temperature afterheat generating system is made up of organic rankine cycle system and cooling recirculation system.Described organic rankine cycle system includes the electromotor 3 that the afterheat heat exchanger 1 being connected by pipeline, decompressor 2, weary gas heat exchanger 4, condenser 5, gas-liquid separator 8, liquid organic working medium pump 9, gas organic working medium pump 10 are connected with described decompressor 2；Condenser 7 that described cooling system includes being connected by pipeline, cold rinse bank 5, water pump 6.The setting height(from bottom) of described liquid organic working medium pump 9 is substantially lower than the setting height(from bottom) of described gas-liquid separator 8.Through the weary gas heat exchanger 4 described in described gas-liquid separator 8 isolated gas entrance, through the liquid organic working medium pump 9 described in described gas-liquid separator 8 isolated liquid entrance.
Described a kind of energy-saving low-temperature afterheat generating system is operationally, organic working medium afterheat heat exchanger 1 in described organic rankine cycle system absorbs waste heat heat and becomes high temperature and high pressure gas organic working medium, high temperature and high pressure gas organic working medium flows to described decompressor 2 and promotes decompressor to rotate, and described decompressor 2 rotates and then drives described electromotor 3 to generate electricity；The most weary gas flowed out from described decompressor 2 enters weary gas heat exchanger 4 and then is passed to by the partial heat of the most weary gas through described gas-liquid separator 8 isolated gas organic working medium；Cool down from the condenser 7 described in the secondary weary gas entrance that described weary gas heat exchanger 4 flows out, be probably neat liquid from the state of the organic working medium of described condenser 7 outflow, be also likely to be gas-liquid two-phase；From the gas-liquid separator 8 described in the organic working medium entrance that described condenser 7 flows out, enter weary gas heat exchanger 4 from described gas-liquid separator 8 isolated gas organic working medium and absorb after the heat of the most weary gas inflow gas organic working medium pump 8 again, be directly entered liquid working substance pump 9 from the described isolated liquid of gas-liquid separator 8；Described afterheat heat exchanger 1 is reentered after described gas organic working medium pump 10 effluent air organic working medium is converged with the liquid organic working medium flowed out from described liquid organic working medium pump 9.Cooling water condenser 7 in described cooling system enters described cold rinse bank 5 after absorbing the heat air cooling of the weary gas of secondary, the cold water of described cold rinse bank 5 is squeezed into described condenser 7 and then completes a cooling circulation by described water pump 6 again, reaches the purpose of cooling water circulation use.The effect of described gas-liquid separator 8 is to make the organic working medium flowed out from described condenser 7 be not necessarily liquid condition completely, also the cooling water flowed out from described condenser 7 is made to there is no need to be discharged to sewer, therefore described a kind of energy-saving low-temperature afterheat generating system, i.e. reach the recycling of the most weary gas heat, also complete cooling water circulation purpose, energy-saving and emission-reduction are had certain significance.
